On 1 July 2012 the Mackay Hospital and Health Service (HHS) commenced operation as an independent statutory body overseen by the Mackay Hospital and Health Board (Mackay HHB).
The Mackay HHB sets the strategic direction and oversees the management of the Mackay HHS. This provides an opportunity to have enhanced local decision making and accountability for the delivery of local health services.
On 22 November 2022, the Governor-in-Council dismissed the Mackay HHB following the recommendation of the Minister for Health and Minister for Ambulance Services and appointed an Administrator Karen Roach for the Mackay HHS.
